Solution Overview

Problem

Manufacturing motorized slewing rings with large diameters is complex due to the need for numerous part adaptations, making production and maintenance difficult, especially for diameters greater than 1 meter.

Innovation Solution

The method involves using standardized magnetic and coiled blocks arranged at regular intervals on two annular rings, where one ring is fixed with coiled blocks and the other with magnetized blocks, allowing for easy modular production and maintenance by exchanging blocks individually without disassembling the entire motorization system. This design simplifies the motorization process by using linear motor blocks and flat annular surfaces for assembly, facilitating the use of the same blocks across different diameters.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If traditional motorization methods are used for large diameter slewing rings, then the motorization can be achieved, but the manufacturing complexity increases significantly and maintenance becomes difficult

Engineering Contradiction:
Improvemanufacturing complexityVSAvoidadaptability to different diameters
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The motorization system is divided into independent modular blocks (magnetic blocks and coiled blocks) that can be individually manufactured and assembled. Each block functions as a self-contained unit with standardized dimensions, allowing the overall motorization to be adapted to different slewing ring diameters by simply varying the number and arrangement of blocks without redesigning the entire system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent establishes universal standardized blocks that can be used across different sleving ring applications and diameters. The magnetic blocks and coiled blocks are designed with standardized interfaces and dimensions, enabling them to serve multiple functions and be interchangeable across various motorized slewing ring configurations, thereby reducing manufacturing complexity while maintaining adaptability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Power

Core Design Contradiction:

Solution Approach 1:

The motorization system is divided into independent modular blocks (magnetic blocks and coiled blocks) that can be individually manufactured and assembled. Each block functions as a self-contained unit with standardized dimensions, allowing the overall motorization to be adapted to different sleving ring diameters by simply varying the number and arrangement of blocks without redesigning the entire system.

Inventive Principle:

Solution Approach 2:

Multiple magnetic blocks and coiled blocks are combined in a standardized modular configuration to achieve the required motorization power. The blocks are arranged in pairs or groups around the sleving ring, with each block contributing additively to the total motor output. This merging of standardized units allows scalable power increase without proportionally increasing system complexity.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of repair

If complete motorization assembly is disassembled for maintenance, then individual blocks can be replaced, but the maintenance process becomes time-consuming

Engineering Contradiction:

Solution Approach 1:

The motorization system is divided into independent modular blocks (magnetic blocks and coiled blocks) that can be individually manufactured and assembled. Each block functions as a self-contained unit with standardized dimensions, allowing the overall motorization to be adapted to different sleving ring diameters by simply varying the number and arrangement of blocks without redesigning the entire system.

Inventive Principle:

Solution Approach 2:

Individual magnetic blocks or coiled blocks can be extracted and replaced independently from the rest of the motorization system. The standardized interfaces and modular design allow blocks to be removed and installed without disassembling the complete motorization assembly, significantly reducing maintenance time and effort while improving repair ease.

AI summary

The ring (1) has an annular fixed inner ring (2) and an annular mobile outer ring (3) rotationally mounted relative to each other along a rotational axis (X) of the ring (1), and a rotational motor e.g. synchronous motor, with a wound part (4) and a magnetic part (5). The wound part includes wound blocks (41) fixed on the fixed ring, where each wound block has an electrical conductor that forms a three-phase winding at each wound part. The magnetic part has magnetic blocks (51) fixed on the mobile ring, where the magnetic blocks having magnets (52) form a ring of magnetic blocks. An independent claim is also included for a method for manufacturing two different types of motorized slewing rings.
